New method for germination of lettuce
Lettuce, lettuce and oily wheat are cultivars of 1-2 year old herbaceous plants of the genus Chrysanthemum. Native to the Mediterranean coast of western Asia, it is a cold-tolerant, cool, and hot vegetable. The seeds can start germination at 4 ° C, and the suitable germination temperature is 15-20 ° C. When the temperature is higher than 25 ° C, it is difficult to germinate due to the water absorption of the seed coat. Therefore, in the summer and autumn cultivation, the seeding period is still in the high temperature stage in summer, and the seed germination is often poor. The method of germination and sowing can be adopted, and the following methods have been proved to have good seed germination effect.
The seeds are wrapped in fine gauze or bean wrap, which is slightly larger depending on the amount of seeds, which is convenient for germination to cleanse the seeds. Pack the seeds in clean, cool water and gently wash them several times to make the seeds fresh and clean. Then soak them with new high-fat film for 2-3 hours, remove the excess water, and wrap them in a refrigerator. Room (5-10 ° C) for 24-36 hours, remove and wash the seeds and towels, wrapped with a wet towel at room temperature (about 20 degrees) to germination, generally after 1-2 days, the seeds can be exposed in large quantities.
Note that all the supplies in the germination process should not be oily, and the hands should not carry oil, so that the seeds breathe. The function of the wet towel is to moisturize. If it is too dry, it will not be moisturizing. If it is too wet, it will affect the seed's breathing. It is not conducive to the germination of the seed.
